Session Replay
- Session Replay
- A technology that captures user interactions on a website or application and reconstructs them exactly as they happened.
Detailed Explanation
Session replay works by tracking changes to the Document Object Model (DOM) and user input events. Unlike screen recording, it doesn't record pixels; it records the "instructions" for the browser to recreate the page. This allows for high-fidelity playback with low bandwidth and perfect privacy controls.
How Relyv helps: Relyv uses a high-performance DOM serialization engine that captures every nuance of the user experience while maintaining a sub-3% performance footprint.
